Energia - Earth's energy management
    ENERGY is a simulation game, done by a Russian geographer working in Portugal. It allows for the management of earth's energy resources during the next 150 years. The game is based on known relationships between variables like mineral resources, pollution, etc., whose values are in part controlled by the user. The initial default inputs are realistic. However, random events may occur during the game... The user is watching progressively the impact of his strategy on the development of human life on Earth... Although the interface is quite simple, the playing may be addictive.
